The Forex Fraus Slogger Expert Advisor is a reversal-based script that identifies reversal trades using the Envelopes Bands indicator. It manages trailing stops of trades opened by the Expert Advisor, as well as trades opened by other Expert Advisors, or manually by the user.
The Envelopes Band indicator provides an Upper Band and a Lower Band in which prices typically trade during sideways markets.
When the price enters the Envelope from outside, it continues to move towards the center of the Envelope, or towards the other end of the Envelope. The EA identifies such scenarios and converts such situations into trading opportunities.
When the price is above the Upper Envelope, and crosses below the Upper Envelope from above, the Expert Advisor generates a SELL trade. The expectation is that the price will continue falling towards the center of the Envelope.
